TRAP FOR FLOOR-BRAINS, SHOWER-BATES, AND THE LIKE.

Specification of Letters Patent.

Patented Jan. 1, 1918.

Application filed July 21, 1917. Serial No. 181,952.

To all whom it may concern:

Be it' known that I, JOHN I. GORMAN, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Traps for Floor-Drains, Shower-Baths, and the like; and I hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will nable others skilled in the art to which it p rtains to make and use the same.

This invention relates to new and useful improvements in floor drain traps, such as are employed in connection with shower baths, wash rooms and the like.

The object of this invention is to provide a trap which, in addition'to serving to carry off the water passing down through the drain, will also serve to collect and carry ofi the waterwhich seeps through the floor adjacent to the drain. I

My invention therefore consists in the features of construction and combination of parts hereinafter described in the specification, particularly pointed out in the claims and illustrated in the accompanying drawings. 1

Referring to the accompanyin drawings, Figure 1 is a central vertical sect1on through a trap embodying my invention. Fig.2 is a section on line 22, Fig. 1. Fig. 3 is a top plan f the floor drain.

Again referring to the drawings, it will be seen that the main portion of the trapis similar to the -traps now in general use and comprises a cylindrical body portion and an S-shaped leg-portion 11. The legportion is provided with the usual screwthreaded connection 12 for receiving the end of the drain pipe. The body-portion 1G and the leg-portion 11 are preferably reinforced by a web 13. ihe main body portion 10 is rovided at its upper end with a horizontai annular flange 15 and is also provided with an interior screw-thread 16 which extends from the rim of the body portion downwardly a short distance. In the top of the body portion is screwed a sieeve or thimble 18. This sleeve is provided with. an annular flange 19 which project out wardly and. horizontally at a point intermediets of the upper and lower ends of said sieeve. The exterior surface of the said sleeve below the said flange 19 is screws to engage screw thread at the top of the bodyportion 10. In the bottom surface of the flange 19 of the thimble 18 is formed a series of radial grooves 20, and in the outer surface of the sleeve below said flange 19 are formed grooves 21, the ends of which register With the inner endsof the grooves 20. There is thus formed in the outer surface of the thinible a series of L-shaped grooves which may be termed drainage ducts. In order to catch the seepage water and conduct it to these drainage ducts, a drip pan, preferably formed from a piece of sheet lead shown at 23, is provided. The piece of sheet lead 23 has an opening at the center thereof approximately the same size as the interior diameter of the body 10, and the piece of sheet lead is laid on top of the flange 15 with the opening therein corresponding to the opening in, the top of the body portion, and the thlmble 18 is then screwed down into the body portion until the flange 19 thereon clamps the piece of sheet lead against the flange 15 on the body portion. This arrangement serves to hold the sheet lead rigidly in position, and the portion of the sheet lead clamped between the flanges 15 and 19 acts as a gasket formin a watertight connection between the thim lo and the body of the trap except where the drainage ducts are provided. It will be readily unde'rstofid that the water which seeps through the floor will fall on the sheet of lead, and, as this sheet is slightly dished, the water will flow toward the trap and enter the grooves 20 and pass down the grooves 21 into the body of the trap. The sleeve 18 is provided with an interior screw-thread and a drainage pipe 25 having an exterior screw-thread is screwed into the sleeve. At the upper end of the drainage pipe is formed a small basin 26 which is rovided with the usual strainer 27. On the interior surface of the drain pipe is formed a pair of lugs 28 which are adapted to be engaged by a wrench or other tool for screwing the drain pipe up or down in the thimble '18 in order to adjust the upper end of the drain pipe relative to the floor.

level.

What I claim is I 1. The combination with a trap having a horizontal annular flange around the rim of the body portion, said body portion being provided with an interior screw thread of a thimble adapted to screw into the body portion, said thimble comprising exterior screw-threaded sleeve having a horizontal annular flange, said thimble being provided with a series of L-shaped grooves in the exterior surface thereof, said grooves extending vertically from the bottom of the'sleeve to the flange and then horizontally along the under side of the flange and a drip pan having an opening registering with the opening in the trap body clamped between the trap body and the flange on the thimble.

2. The combination with a trap having a leg portion and a body portion, the body 'portion being provided With an annular horizontal flange at its rim and an interior screw thread adjacent to the rim of a thimhle adapted to screw into the body portion of the trap, said thimble having a horizontal annular flange intermediate of its ends and being provided with L-shaped grooves in its exterior surface, said grooves extending vertically up the lower end of the thimble and horizontally along the bottom surface of the flange, and a sheet metal plate having an opening registering with the opening in the body portion of the trap arranged on the body portion and overlapping the flange on the body portion and forming a pan for catching the seepage water and conducting it to the L-shaped grooves in the thimble.

3. The combination with a trap having a leg portion and a body portion, said body portion having an annular flange at its rim and an interior screw thread of a thimble arranged to screw into said body portion, said thimble having an annular flange corresponding to the flange on the body portion and an interior screw-thread, said thimble being provided with a series of L-shaped grooves on the exterior surface thereof, said grooves extending vertically upward from the lower end of the thimble to the flange and horizontally along the bottom of the flange, a dislrshaped sheet of lead arranged on top of'the body portion, said sheet of lead having an opening registering with theopening at the top of the body portion, the portion of the lead sheet which overlaps the flange on the body portion forming a gasket and the dish-portion of the sheet of lead providing means for catching the seepage water and returning it to the trap by way of the L-shaped grooves and a drain pipe adapted to screw into the thimble so as to be adjustable therein.

In testimony whereof, I sign the foregoing specification, in the presence of two witnesses.

JOHN I. GORMAN.
